COMBINED ADDING AND IPBINTING Application filed May 5, 1925, Serial No. 28,110, and in Germany November 99, 1928.

This invention relates to that type of adding and printing machines, in which the fig; ure keys themselvesconstitute stops co-operating with elements each of which is on y provided with a single stop or projection.

The essential feature of the invention consists in the fact'that the rows of keys are located in the same plane as the ty e barsor type carriers which are placed si e by. side at the normal distance apart for printing, and that the keys are arranged at the same distance behind one another as that separating the type on the type bars from one another. I I

By reason of the smallness of the heads of the r operating device or key rod may be provided ual keys-are actuated.

Other features of the invention will be brought out clearly in relation to the de-.

scription of the drawings, and will he defined more particularly' in the appended claims.

The object of the invention is to produce a small handy machine which, while being of light weight, necessitating only a small expenditure of materials and consequently heing cheap, givesthe same results as the well known forms of adding machines.

The inventionis illustrated by way. of example in the accompanying rawings, in wh1ch:- .1 V Fig. 1 is a sectional side elevation with the parts in the out of use or inoperative position. r

Fig. 2 is a similar View with some of the parts in the operative position.

Fig. 3 shows the'operating and driving mechanism.

. Fig. 4 is a top plan of the working parts of the machine.

Figs. 5, 6 and 7 are details hereinafter referred to. r "i Fig. 8 shows the operating and driving mechanism from the opposite side to Fig. 3.

Figsr9 to 15.show various 0 rative po sitions, seen from the right an thelefh,

The ke s l which are arranged in the manner 0 a clTess hoard (see Fig. 4) are provided with stems 2 whichpass at upper and lower levels through cut away portions of rods 3. 4 is a spring for holding the key in the upper position. The rods 3 are ineys over the whole keyboard, owing to' the foregoing construction; a special key given the necessary rigidity.

The locking bars 11 pass through and are guided by cut away portions in, the transverse struts '6. These bars hold the keys in rod, so that in this way the the setor depressed positions in the gordi nary way.

. At their reduced right hand ends, as

portions 12 (see Fig.4) Against this turned over portion 12 is adapted to bear one arm of the locking hook 13, which is shaped as a bell crank lever, the lower arm of yvhich is kept pressed downwards by means of a compression spring 14.- In this way the vertical arm is spring pressed towards-the right, so that the corresponding locking bar 11 is also always kept pressed towards the right and against'the transverse struts 6.] I

'When a ke is, pressed down, as shown at Fig. 2, a hoo on the locking bar takes over the bent over ortion of the stem of the key and locks the ey down. .If another key is set, the key already depressed is released,

in 'a'well" known manner. 16 is-a rocking deviceagainst which the prolonged. ends 15 of the lockingbars are adapted to rest so that by rockin over this device all the keys can be release/i I 18 aredifi'erential bars, one of which is towards one end 'by the strut 17 of the framework and towards the other end by the strut 6. The projecting pieces 19 are attached to these bars. The upper or short-4 or end 19of aprojecting piece is adap to come against the lower end of the stem of a key when depressed. The bar can follow the pull of a sprin 20, which is con- ,nected to the lower an longer end of the projecting piece 19. Underneath the locking hook 13, the bar 18 is provided with notch 21 with which the locking hook 13 is adapted to engage in the position shown at; Fig. 1, when'none of the .keys are depressed.

.in Fig. 1, they are provided with bent overv located'under each row of keys and guided X 4 vsssvavehaste com This engagement of thelocking' hook in the notch causes the difierentialhartoibe held l thatof restxand the settin fast. If however, as'shownxat'Fig. 2, a. key is set or depressed, thenthe lockinghook is 5 disengaged by means of the locking bar 11 The locking l3 continues raised when the locking bar -11. is'in a position between of a key:

"As has already been sta ed, those ofjihe difl'erentialbars- 18 which are in the plane of keys which have been depressed, have a I tendency to yield to the pull of the spring,

but are in thefirst instance retainedin position by the hail 22, which is carriedby allel and on'.. both sides, so, .;thatthe mcansof elbow levers 23,24 arranged arail slides in slots 25 on the side walls, see Figs.

'1 During thel rnovement of the bar 18ito-,- 1 wards the left-1 the 'counter'30 is out of en 'jgagement. In this position .QQChOfdthC counter iVheels is held from" rotationfhy l means, of a fixed toothv or projection '31;

The cmmtcn wheels 30 are located in a: franie 33. oscillating about an axle 32. l Thedown ortion of this frame. is provided with a" p n '34,; one 'o'f-these being provided atfeach side'of theframe, as-in .wnrdly extending fact most of the elements are (implicated on each side in order to preserve parallelism in action, the parts being provided on hoth sides of the machine. j v

The return of the hand lever 28 is caused by the tension spring 35, and during the'.re-' turn the bail 22 passes overan 'incline36 'on the slot 25 and moves the pushbari 37 in the longitudinal direction, this bar strik ing against the pin 34 and throwing in the counter. The spring 39 moves the bar 37 v towards the left -(see Figs. 2 and 3)' and upwards. The position-to the left is gov-v whilst the pin 34 preventsupward m'oveerned by the pin 40. fixed to the casing,

3T0 the lowerextension of the frame 33 is pivoted a bolt 38, which is under the pull of a sprin 41, so that it has a sprin upward ten ency, which tends to. hol the counter out of engagement with the. difierential bars' 18, see Fig. 8. When however the bail 22 moves backwards, it pushes the bars 37 towards the right; and these, with their right hand ends Strike the pins 34 and throw in the counter, as shown at Fi 2 and 12,- in which position it'is secure? tionsl42 over the pin 40. The bail 22 is moved towards the right spring 35 and comes i'nto contact in sucv 3"" the bolt 38 which engages'with its'proje'm,

As the wheelsofzthecountez when thrown in, sink down, theyarefreed froni the tooth or projection ,31 and can turn without hindrance. As soon asfthe bail 22 reaches tha end ofits pathor draws near the end; it moves downwards over an incline -44 'of the slot25 and when it comes'into the lower- -down-Wards, the result being that'the counter is-again' released and raised by the springs 41,

BEEN AVAZLABLE COP":

' pushes the lever 49 downwar s, in which position it is held by the hook 51. The bent. over portion 48 in this way comes out of the reach of the toothed rack 43, and this latter springs towards the right, and as a lever 49 of a counter wheel of lower denomination is released, causes a transfer or carrying over of 10. All the toothed racks 43 which have effected a transfer have moved towards the right, so that their projections 47 have come i against the transverse struts 17; moreover all the bars 18 have moved out of their normal'position shown in Fig. 1 through one step further towards the right, which has been caused by the additional distance through which the bail 22 has passed, as indicated at Fi 8.

'In order that the machine may be ready for fresh additions,-the bail 22 and the bars .18 and rack 43 must again take up their original'positions as shown in Fig. 1.;' in other words the bail. 22 must, after each operation of the leveroroperating handle ,s ring backwards through a step towards I t cleft.

This operation is effected by means of the L-shaped slot 52 (Figs. 3 and 8) at the end of the connecting rod 26, in which a pin on the arm 27 engages ,l Vhen-the hand lever 28 afterit has been pressed down by the handle is brought back by the pull of the spring 35, at which time, as already stated,

,the bail 22 pushes back the bars 18, and

' shortly before the said bail 22. reaches its lowermost position the connecting rod 26 strikes the fixed projection 53, whilst the pin on the lever 27 swings further over, which causes it to be brought out of the vertical into the horizontal opening (Fig. 3), the result being that the bail 22 springs back together with the bars 18 into the normal position owing to the pull of the spring 20 and ultimately the arm 27 and at the same time the hand lever 23 comes against the liked projection 53. l The counter is at this time disengaged and the toothed racks 43 and bars 18 ha re come into a position for ai -Fresh operation. The incline 44, over which the hail 22 passes,

has for its object more easily to overcome the resistanccfof the springs 45. These springs have all to be'slrcssed if'thc ,lil'lumfilfills l7 arc not turned out off-the way, WlllCll rc quires a considerable expenditure of power.

The differential bars 18 are provided at their left hand end with teeth, on the underside, wi'th which they engage a toothed .Wheel 54, which wheel is in fixed connection with another toothed wheel 55, with which meshes a type bar 56. The consequence'is that a type bar 56 participates in the movement of the differential bar 18, and, as the distance between the printing type corresponds to the distance between the keys, the type bar is brought through the depression of the key into a position corresponding to the value on the key set.

it has been mentioned in passing that the locking bars 11, in the locking position, when released by the locking hooks 13 take up a different positionfrom that which they occupy in the rest position. This dilierence of position is utilized for the purpose of cansing zeros locatedon the left not to be printed: Each of the locking bars-11 is provided at its left hand end with an extension 57 (Fig. 1) against which a bent out portion of a bell'crank lever 59 pivted upon an axle 58 contacts. The longer arm of this bell crank lever, when no key is depressed, is in the lower position, as shown in Fig. 1, but when the key is set'it'israis ed into the upper position as shown in Fig. 2. Pivotally connected to the longer-arm of the bell crank lever 59 is a slidable pushing link 60, which engages by means of a forked portion over the type barnnd is guided thereby. At the upper end it carries an anvil 61 which, when, no key is set is not struck by the hammer 62, but which is struck thereby when a key is set. I

When the type bars-have been brought into position, the hammers 62 are released and cause those bars to print, the anvils 6t ofwhich are within the'reach of the lion wardly' projecting portions 63 of the bane more, see the dotted position in Fig. 2. In order aLthe same time to print zeros coming on the right, when the number has been set towards the left, the push links 60 are rovided with lateral'projections 63-(see. igs.

5m 7), which constitute in a'well known manner a so-called operative bridge, the. resnltbeing that when a push linkfil) loalcd towardsthc left moves upwards; those located towardsthe right move therewith. The slepli ion a luinnper, ivhen the corresponding anvil has not been brought into the operative position. strikes against the guide struts- (35, as shown dotted in Fig. 1, so that imprinting is caused.

For. tllogpurpose of printing the total set on the figure drumslhc following menus are provided.-
